OBJECTIVE: To compare outcomes of externally supported polytetrafluoroethylene (PTFE) grafts and femoral vein as conduits for femoro-femoral crossover grafts. METHODS: This is a retrospective review of consecutive femoro-femoral crossover grafts at our institution between January 2005 and March 2016. Patient demographics, indications, complication rates, patency rates and survival rates were compared between femoro-femoral grafts created with either PTFE or femoral vein conduits, autogenous or cryopreserved...

The population is aging, and the prevalence of chronic wounds is increasing. Because neovascularization is essential for tissue repair and both local and systemic factors affect new blood vessel formation, we hypothesize that altering either pathway would reciprocally enhance wound healing in the aged. To test this hypothesis, p53 was locally suppressed and endothelial progenitor cells (EPCs) were systemically mobilized in a murine model of senescent wound healing.Bilateral 6-mm full-thickness stented wounds were made on the dorsum of Zmpste24 mice...

Topical nitric oxide (NO) delivery has been shown to accelerate wound healing. However, delivering NO to wounds at appropriate rates and doses requires new biomaterial-based strategies. Here, we describe the development of supramolecular interpolymer complex hydrogels comprising PEO-PPO-PEO (F127) micelles embedded in a poly(acrylic acid) (PAA) matrix, with S-nitrosoglutathione (GSNO) molecules dissolved in the hydrophilic domain. We show that PAA:F127/GSNO hydrogels start releasing NO upon hydration at rates controlled by their rates of water absorption...

INTRODUCTION: Calciphylaxis is a rare condition including patchy dermal necrosis that mostly affects chronic hemodialysis patients. The syndrome usually heralds impending death although patients may survive following a set of measures including an adapted dialysis regimen. The present case is a unique patient who recovered from an earlier episode of upper leg calciphylaxis 5 years previously but developed fatal bilateral breast necrosis. PRESENTATION OF CASE: A 69 year old Caucasian woman with a history of atrial fibrillation, hypertension, CVA, hyperparathyroidectomy for secondary hyperparathyroidism and end stage renal disease with hemodialysis recovered in 2012 from extensive symptomatic left upper leg necrosis due to calciphylaxis...

Skin tumors have been observed in C3H/HeJ mice following treatment with high and strongly irritating concentrations of 2-ethylhexyl acrylate (2-EHA). Dermal carcinogenicity studies performed with 2-EHA are reviewed, contrasting the results in two mouse strains (C3H/HeJ and NMRI) under different dosing regimens. Application of contemporary evaluation criteria to the existing dermal carcinogenicity dataset demonstrates that 2-EHA induces skin tumors only at concentrations exceeding an maximum tolerated dose (MTD) and in the immune-dysregulated C3H/HeJ mouse model...

Complex coacervates based on natural biopolymers have been explored as a protein delivery system to provide controlled release of loaded protein and circumvent its proteolytic degradation in chronic wounds. The coacervates composed of gelatin A (GA) and sodium alginate (SA) were optimized with respect to turbidity, size, zeta potential, and polydispersity index. Bovine serum albumin (BSA), a model protein, was effectively encapsulated in the coacervates, resulting in protection from trypsin digestion and controlled release...

Reactive species of oxygen (ROS), responsible for oxidative stress, accumulate in various tissues damaged by burns, decubitus ulcers, and vascular lesions. Antioxidants play an important and well-documented role in healing of chronic and acute wounds. Rigenase® , a specific extract of Triticum vulgare manufactured by Farmaceutici Damor, is employed in products used for the regeneration of tissue injuries. In this work, we show that Rigenase® exhibits a scavenging effect toward free radicals, thus pointing to its relevant antioxidant activity...

Glucocorticoids are a mainstay for the treatment of immune-mediated conditions and inflammatory diseases. However, their chronic use causes numerous side-effects including delays in corneal and cutaneous wound healing. This is attributed to off-target agonism of the mineralocorticoid receptor, which can be reduced by co-administration of a mineralocorticoid receptor antagonist such as spironolactone. The aim of this study was to develop a fast, selective and sensitive UHPLC-ESI-MS method for the simultaneous quantification of spironolactone, its active metabolites - 7α-thiomethylspironolactone and canrenone, the latter's water-soluble prodrug potassium canrenoate, and the synthetic glucocorticoid, dexamethasone, in corneal samples (17α-methyltestosterone served as an internal standard)...

Macrophages play key roles in all phases of adult wound healing, which are inflammation, proliferation, and remodeling. As wounds heal, the local macrophage population transitions from predominantly pro-inflammatory (M1-like phenotypes) to anti-inflammatory (M2-like phenotypes). Non-healing chronic wounds, such as pressure, arterial, venous, and diabetic ulcers indefinitely remain in inflammation-the first stage of wound healing. Thus, local macrophages retain pro-inflammatory characteristics. This review discusses the physiology of monocytes and macrophages in acute wound healing and the different phenotypes described in the literature for both in vitro and in vivo models...

Hidradenitis suppurativa (HS) is a chronic, inflammatory, and recurrent skin disease. Surgical excision of wounds appears to be the only curative treatment for the prevention of recurrence of moderate to severe stages. Magnetic resonance imaging (MRI) is a standard reference examination for the detection of HS peri-anal inflammatory fistula. In this case study, the use of real-time medical infrared thermography, in combination with MRI as appropriate imaging, is proposed. The aim is to assist surgeons in the pre- and peri-surgical management of severe perianal hidradenitis suppurativa with the intent to ensure that all diseased lesions were removed during surgery and therefore to limit recurrence...

The postoperative care of animals implanted with mechanical circulatory support devices is complex. The standard of care requires continuous monitoring of hemodynamic parameters post implant, wound care, and maintenance of the animal's well-being, but also includes controlling the animal's biomechanics under conditions of continuous restraint and harnessing. In such studies, a harness provides secure fixation of the exteriorized device driveline and pressure lines and aids animal handling (lifting, position adjustment, and assistance with standing up)...

Silver has emerged as an important therapeutic option for wound infections in recent years due to its broad spectrum antimicrobial activity. The silver cation (Ag+ ), but not the bulk metal (Ag0 ), is highly toxic for most microorganisms although resistance due to genetic modification or horizontal gene transfer does occur. Pseudomonas aeruginosa , however, achieves silver resistance by producing the redox active metabolite pyocyanin that reduces Ag+ to non-toxic Ag0 Pyocyanin also possess broad spectrum antimicrobial activity...
